Abstract
Endrings- og konskvensanalyse i moderne arkitekturelle rammeverk
[Impact and Consequence Analysis in Modern Architectural Frameworks]
Vi skal se på hvordan nyere arkitekturelle prinsipper kan hjelpe analysere konsekvenser av
design/arkitekturer, samt konskevenser av endringer på eksiterende design/arkitektur. Mer
spesifikt, skal vi se på det som er med på å gjøre slike konsekvensanalysene letter i disipliner
som forretningsarkitektur(Business Architecture, BA), forretningsprosesstyring (Business
Process Manager, BPM), og tjenesteorientert arkitekur (Service Oriented Architecture, SOA).
[We will be looking at how newer architectural principles may help analyze consequences of a
design/architecture, as well as the potential impact of changes on existing design/architecture.
Specifically, we will be looking at the enablers inherent in Business Architecture (BA), Business
Process Management (BPM) and Service Oriented Architecture (SOA).]
Keywords - Impact & Consequence Analysis
or CHANGE as a non-functional (f. ex. System Quality) requirement
Planning for CHANGE, managing CHANGE
Impact management (part of change management)
Example: down-time minimization, non-invasive and/or nondisruptive change implementation...
Impact analysis (also simulation, estimation)
Change control
Change anticipation, prediction, risk planning (part of risk
management)
Requirements/prerequisites for change planning & management:
Where is the information we need for predicting/estimating &
managing change?
Road Blocks
What does NOT help us realize predictability, impact analysis, change
management, system quality assurance/control etc?
COMPLEXITY...
Difficult-to-master technologies
Sheer size, large number of (un-documented) relationships
Systems implemented using technologies (with their implied
architectures) that do not expose their logic (or their lack of logic),
their assets and relationships between their assets
Hard-wired systems (i.e., systems that do not lend themselves to
change & interoperability easily)
Lack of standardization

Considerable Value
BPM/SOA technology Simplified:
Reduced to to a simple paradigm -”service-to-service”
EAI, orchestration, choreography addressed in one go
BPM/SOA development paradigm unified:
Development reduced to only 5 abstractions
Patterns used
Time/effort & risk reduced considerably
Paradigm loosely coupled from technology/platform:
All abstractions XML structures

The Cloud: One of many definitions
“Cloud computing is a model for enabling convenient, on-demand
network access to a shared pool of configurable computing
resources (e.g., networks, servers, storage, applications, and
services) that can be rapidly provisioned and released with
minimal management effort or service provider interaction. This
cloud model promotes availability and is composed of five
essential characteristics, three service models, and four
deployment models”.
Benefits? On-demand self-service, Broad network access, Resource pooling, Rapid
elasticity, Measured Service
Cloud from a Services Point-of-View? IaaS, PaaS, SaaS
Cloud Deployment Types? Private, Community, Public, Hybrid
